Cisco Unity Express contains a flaw that allows a remote Cross-site Request Forgery (CSRF / XSRF) attack. The flaw exists because the application does not require multiple steps or explicit confirmation for sensitive transactions for the CUEreload (and other) forms accessed via /Web/SA/SaveConfiguration.do. By using a crafted URL (e.g., a crafted GET request inside an "img" tag), an attacker may trick the victim into clicking on the image to take advantage of the trust relationship between the authenticated victim and the application. Such an attack could trick the victim into restarting the device, or possibly taking other unspecified actions, in the context of their session with the application, without further prompting or verification.
